AEco Afect 125 0007 T500

Entity layer: Viewer\_risk\_flood This layer of entities contains different layers of information to reflect the dangers and risks that a flood regime entails in the 3 zones that according to the member states have a Significant Potential Flood Risk. For each of the 3 zones there are the following layers of information: · Ptos EImp: Points of particular importance · Pobl Afect: Affected population · ZI: Flood Zone · Preferred Flow Zone · Hydraulic Public Domain · IAmb area: Area of environmental interest · AEco Afect: Economic Activity Affected All the previous layers, except the Preferred Flow Zone and the Hydraulic Public Domain, are drawn for a return period of 100 and 500 years. In the Points of special importance, specific conditions are described to car parks, hotels, health center, archaeological, trails, historical complex, etc. Each of the affected points is given a qualifier of: Mild, Grave, Very Grave. The affected population layer gives us information on the number of inhabitants affected by the flood, and the total population of the municipality, to know the percentage of affection of the municipal population. The Flood Zone gives us the surface that is occupied by water in a regime of one flood for the two periods of return. This layer specifies that, this layer was calculated with the IBER and that the source of the calculations was made on an MDT with an accuracy of 1 meter by 1 meter of LIDAR (GRAFCAN). The preferred Flow Zone is a layer that draws the polygon that is most often occupied by water when the ravine runs within its channel. The Public Hydraulic Domain is established with a return period of 100 years and with the infrastructure available to stop or reduce the effect of water. Two distinct zones are established that are the Public Hydraulic Domain (DPH) and the bonded zone, which are 5 meters from the DPH to each of the two margins of the channel. The Area of Environmental Interest is a layer that indicates the protected areas that will be affected by a flood of the riverbed, and indicates what type of condition has the possibility of occurring. The Affected Economic Activity divides the affected area into different areas according to the type of activity, such as agícola-regadío, urban, forest, bodies of water, etc. establishing an estimated economic damage in euros for each of them and an area of affection for each of them. All these layers described above are repeated for each of the fluvial arpsis, which in the case of La Palma are: the ravine of Las Nieves, the ravine of Las Angustias and the ravine of La Paloma.
